Invaders from the Infinite by John W. Campbell (well read books .txt) 📕

“Do you understand? That is the principle on which your ship operated. There were two time-fields, overlapping time-fields. Remember the terrible speed with which your ship landed, and yet there was no appreciable jar according to the men? The answer of course was, that their time rate had been speeded enough, due to the fact that one field had been completely shut off, the other had not.

“That is the principle. The system is so complex, naturally, that we have not yet learned the actual method of working the process. We must do a great deal of mathematical and physical research.

“Wish we had it done⁠—we could use it now,” mused the terrestrian.

“We have some other weapons, none as important, of course, as the molecular ray and the heat ray. Or none that have been. But, if the enemy have ray shields, then perhaps these others also will be important. There are molecular motion guns, metal tubes, with molecular director apparatus at one end. A metal shell is pulling the power turned on, and the shell leaps out at a speed of about ten miles per second⁠—since it has been super-heated⁠—and is very accurately aimed, as there is no terrific shock of recoil to be taken up by the gun.

“But a more effective weapon, if these men are as I expect them to be, will be a peculiarly effective magnetic field concentrator device, which will project a magnetic field as a beam for a mile or more. How useful it will be⁠—I don’t know. We don’t know what the enemy will turn against us!”

After Morey’s explanation of the ship was completed, Wade took Arcot’s place at the controls, while Morey and Arcot retired to the calculating room to do some of the needed mathematics on the time-field investigation.

Their work continued here, while the Ortolians prepared a meal and brought it to them, and to Wade. When at last the sun of Ortol was growing before them, Arcot took over controls from Wade once more. Slowing their speed to less than fifty times that of light, they drove on. The attraction of the giant sun was draining the energy from the coils so rapidly now, that at last Arcot was forced to get into normal space, while the planet was still close to a million miles from them. Morey was showing the Ortolians the operation of the telectroscope and had it trained now on the rapidly approaching planet. The planet was easily enlarged to a point where the features of continents were visible. The magnification was increased till cities were no longer blurs, but truly cities.

Suddenly, as city after city was brought under the action of the machine, the Ortolians recognizing them with glad exclamations, one swept into view⁠—and as they watched, it leapt into the air, a vast column of dust, then twisting, whirling, it fell back in utter, chaotic ruin.

Zezdon Fentes staggered back from the screen in horror.

“Arcot⁠—drive down⁠—increase your speed⁠—the Thessians are there already and have destroyed one city,” called Morey sharply. The men secured themselves with heavy belts, as the deep toned hum of the warning echoed through the ship. A moment later they staggered under an acceleration of four gravities. Space was dark for the barest instant of time, and then there was the scream of atmosphere as the ship rocketed through the air of the planet at nearly fifteen hundred miles per second. The outer wall was blazing in incandescence in a moment, and the heavy relux screens seemed to leap into place over the windows as the blasting heat, radiated from the incandescent walls flooded in. The millions of tons pressure of the air on the nose of the ship would have brought it to a stop in an instant, and had it not been that the molecular drive was on at full power, driving the ship against the air resistance, and still losing. The ship slowed swiftly, but was shrieking toward the destroyed city at terrific speed.

“Hesthis⁠—to the⁠—right and ahead. That would be their next attack,” said the Ortolian. Arcot altered the ship’s course, and they shot toward the distance city of Hesthis. They were slowing perceptibly, and yet, though the city was half around the world, they reached it in half a minute. Now Arcot’s wizardry at the controls came into play, for by altering his space field constants, he succeeded in reaching a condition that slowed the ship almost instantly to a speed of but a mile a second, yet without apparent deceleration.

High in the white Ortolian sky was a shining point bearing down on the now-visible city. Arcot slanted toward it, and the approaching ship grew like an expanding rubber balloon.

A ray of intense, blindingly brilliant light flashed out, and a gout of light appeared in the center of the city. A huge flame, bright blue, shot heavenward in roaring heat.

Seeing that a strange ship had arrived was enough for the Thessians, and they turned, and drove at Arcot instantly. The Thessian ship was built for a heavy world, and for heavy acceleration in consequence, and, as they had found from the captured ship, it was stronger than the Ancient Mariner. Now the Thessians were driving at Arcot with an acceleration and speed that convinced him dodging was useless. Suddenly space was black around them, the sunlit world was gone.

“Wonder what they thought of that!” grinned Arcot. Wade smiled grimly.

“It’s not what they thought, but what they’ll do, that counts.”

Arcot came back to normal space, just in time to see the Thessian ship spin in a quick turn, under an acceleration that would have crushed a human to a pulp. Again the pilot dived at the terrestrian ship. Again it vanished. Twice more he tried these fruitless tactics, seeing the ship loom before him⁠—bracing for the crash⁠—then it was gone instantaneously, and though he sailed through the spot he knew it to have occupied, it was not there. Yet an instant later, as
